Instead of hard coding constants into the math of a program, making them into variables makes it
much easier to change them in the future.

Question

The statement is asserting that substituting hard-coded constants with variables (often named, configurable constants) makes future changes easier. This is a sound coding practice for several reasons.

First, using named constants or configuration values improves readability. When you see a variable like MAX_CONNECTIONS or PI rather than a raw 42 or 3.14159 scattered through code, it’s clearer what the value represents and why it exists.

Second, it enhances maintainability. If you need to adjust a value, you can change it in one location (where the constant is defined) rather than hunting down every occurrence of the literal number throughout the codebase. This reduces the risk of inconsistent updates and mistakes.

Third, it supports flexibility and reuse. Values that are parameterized can be driven by configuration files, environment variables, or user input, enabling the same code to operate under different scenarios without recompiling.

Fourth, it aids testing and deployment. By centralizing constants, you can swap them for testing doubles or tweak them for different environments without altering the core logic.

Finally, this practice also reduces the chance of errors due to typos or misremembered numbers, since the constant name acts as a single source of truth.

In contrast, hard-coding constants directly into formulas ties the behavior of the program to those exact numbers, making changes labor-intensive and error-prone.

Therefore, the statement aligns with common software engineering guidelines and is considered true in the context of writing maintainable, flexible code.
